UN Reports Record-Breaking Extreme Heat and Global Impacts

The World Meteorological Organization (WMO) released a report highlighting record-breaking extreme heat worldwide and its severe impacts.

• July 2025 was the third-warmest July on record, with heatwaves causing approximately 489,000 annual heat-related deaths globally between 2000 and 2019, heavily affecting Europe and Asia.
• WMO is advancing heat early warning systems and collaborating with UN agencies under the Secretary-General’s Call to Action on Extreme Heat, aiming to limit global warming to 1.5°C and save nearly 100,000 lives annually by scaling heat-health warning systems in 57 countries.
